Device Drivers For Mac Os X

Hello you MAC Techy Guys. I have never had a MAC although I am trying to sort out a friends MAC. I have only been using PC's for many many years ( Green screen IBM's to Intel i7 ) so you can imagine how different it is for me. So apologies if this has been asked a hundred time but I have searched and searched but never found a reasonable answer ( lots of silly ones )
In the Windows system there is Device manager where if a device has a problem you can inspect the driver and try and update it etc and see what the results are.
In the MAC world it does not seem to exist in the same way. I did ask this question in another MAC forum but was told.. 'MAC doesn't need it' and 'If the device don't work buy a different type' ... which is not really the type of technical answer that I hope you may be able to explain
Example.. in Leopard 10.5 ( I think ) I connected a USB wireless device ( Ralink ) when the MAC system was running.. There is no screen indication of any drivers being detected which it what I expected.. I looked into the system profiler and can see the USB WiFi device and it various specs. I can load the MAC Ralink software from the install disk and then look for the Application which is listed.. If I try and launch it, it says the device does not exist !!!
How do you try and see if the drivers are loaded. In Windows there is the Yellow exclamation mark but on the MAC nothing.
I guess there is a very simple explanation to this but for a new MAC user a nightmare
I do realise this sounds like a very novice question and I hope I wont feel too embarrassed when you tell me how these sort of problems are solved on a MAC OS
Thanks in advance
John
